In general, this occurs because you have some other libraries (from your system) that link against libcrypto.so.1.0.0. In theory, it should all just work, but in practice I've often found my application did not work as expected.
Specifically, I'd get a TLS end point that did not speak ECDSA (1.0 does not, 1.1 does). You have make a pass through the shared objects that your application references (ldd output), and then using ldd, you can discover which ones want libcrypto.so.1.0.0, and then you either have to upgrade those libraries, or you may have to compile them from source. The last time I did this, I found it was libpqclient5 (a postgresql client library), and that I was able to upgrade it to libpqclient10 rather than resort to source code. Minimal distributions like containerized alpinelinux also help to minimize your dependancies. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] m...@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
